Yokohama, Japan A rotary atomizer electrostatic coating apparatus having a spray head main body made of an elec- trically insulating material; and a plurality of discharge electrodes having a nearly band-form pat· tern extending outward approxi- mately along the rear side shape of the spray head main body. ULTIIASONIC CUAIlIING APPARATUS U.S. Patent 5,865,199. Feb. 2, 1999 M.P. Pedziwiatr, Greenwood Lake, N. Y., and E.A. Pedziwiatr, Cresskill, N.J. An improvement in ultrasonic cleaning apparatus in which arti- cles to be cleaned are immersed in a bath subjected to ultrasonic en- ergy emanating from ultrasonic transducers coupled to a wall con- tiguous with the bath, the im- provement comprising first trans- ducers for providing ultrasonic energy at a first ultrasonic fre- quency; and second transducers for providing ultrasonic energy at a second ultrasonic frequency dif- ferent from the first ultrasonic frequency; the first transducers set being interspersed with the second transducers. barrier preventing the vaporized solvent from escaping the tank; and a single refrigeration unit, which can be switched to operate in two different modes and is con- structed and arranged to provide a flow of low-temperature refrig- erant to the secondary solvent condenser, low-temperature re- frigerant to the primary solvent condenser, and high-temperature refrigerant to the secondary sol- vent condenser.
